Add support to select directories when using @ to select files

What feature would you like to see?

The @ command works great for files but if i want to pass entire directories as context, or refer to some directory i just have to type out the name of the directory and the model has to run bash commands to get the directory and read the files.
It would be nice to have the option to pass directories using the @ command

Are you interested in implementing this feature?
